摘　　要：基于时域有限差分法,研究了利用EBG结构减小手机辐射对人脑的影响。本文提出一种新型的平面型EBG结构,其结构为四周开槽型的方形贴片。将其加载到手机PIFA天线上,然后利用SEMCAD软件,在加载和不加载两种情况下,分别对人脑特定比吸收率(SAR)进行仿真分析和计算。分析结果表明:通过有效使用EBG结构加载技术,可以明显降低手机天线对人体方向的辐射,同时降低人体比吸收率SAR值。Based on finite-difference time-domain(FDTD) method,the effect of mobile phone integrated with EBG structures on human health is analyzed in this paper.A new umplanar EBG structure is presented,whose unit cell is composed of a square patch with slits on each side.The simulation analyses of the specific absorption rate(SAR) of PIFA antenna on mobile phone with and without EBG structures are made by using SEMCAD software.The result shows that the reduction of the radiation towards the direction of human head and the SAR value by integrating EBG structures with mobile phone effectively.
